NON-REFILLABLE BOTTLE.

SPECIFICATION forming wart of Letters Patent No. 783,120, dated February21, 1905.

Application filed May 18, 1904. Serial No. 208,629.

To all whom it may concern.-

Be it known that we, ALEXANDER GEORGE LEDERER and HARRY BENNETT DE FORD,citi- Zens of the United States. residing at Louisville, in the countyof Jefferson and State of Kentucky, have invented new and usefulImprovements in N on-Refillable Bottles,of which the following is aspecification.

Our invention relates to non-refillable bottles;'and it is our object toprovide a bottle that is proof against fraudulent refilling when onceemptied of its original contents.

In the accompanying drawings, Figure 1 is,

a front elevation, partly in section, showing the neck of our bottlewith stopper inserted. Fig. 2 is a top plan view of the same withstopper removed. Fig. 3 is a vertical section taken on the line :1: ofFig. 2. Fig. 4 is a bottom plan view of the stopper. Fig. 5 is a sectiontaken on the line 3 y of Fig. 4. Fig. 6 is a side view, partly insection, showing the neck of the bottle tilted, the mouth, and theposition of the valve in its cage or shell when open. Fig. 7 is amodification of the guardstopper.

Referring more particularly to the drawings, A designates the neck ofthe bottle, formed with an annular shoulder a and an L- shaped groove(0' upon its interior wall, the

' horizontal portion of which runs quarter-way 4 denotes an offset orl1pin the neck, forming a mouth (0 B denotes the stopper, having theknob b on top and a rectangular stud 7), projecting from one side, whichregisters with the L-shaped groove a and forms therewith a bayonetjoint.Below the face of the stopper it has one side out under or formed intothree walls, which meet at obtuse angles, as shown in Fig. 5. \V hensaid stopper is in place, said walls, with the lip a inner adjacent wallof the neck, and shoulder a, form a crooked passage-way leading to thevalve hereinafter described.

C denotes a funnel, made of aluminium or other suitable material, whichforms the shell for the valve, its vertical walls fitting snugly withinthe neck and bent at right angles to form an annular flange 0, by whichit is supported upon the shoulder a. The lower end of said funnel isturned upward and fastened into a washer 0, made of wood or othermaterial, having an annular groove therein, into which is secured arubber gasket 0 which bears in an annular groove formed in the lowerwall of the bottleneck, forminga water-tight joint therewith. 0' denotesa narrow annular ledge brazed to the inner walls of the lower part ofthe funnel.

E denotes a pear-shaped valve the sides of which conform to thecontracted portion of the funnel onto which it seats, as shown in Fig.1.

E denotes a valve-stem depending from said valve. 6 denotes a thin fiatsteel spring rigidly secured midway its length to said valvestem,crossing the same at right angles, and of a length slightly exceedingthe diameter of the lower end of funnel.

F denotes a divided guard stoppcr suspended from the lower end of thevalve-stem and adapted to fit snugly into the lower end of the funnel.It may be made of cork or consist of two hollow members made ofaluminium and hermetically sealed.

In Fig. 7 we show a modification in the arrangement of guard-stopper F,in which G denotes a cork stopper mounted in a conicalshaped cup g upona wooden base 9. valve stem passes through the cork and wooden base andis fastened to the bottom of the cap.

After the bottle is filled the funnel (1, containing the valve and itsattachments, is pressed into the neck of the bottle, carrying with itthe washer 0, until its gasket 0 fits into the annular groove in thelower partof the neck, when the flange 0 seats itself upon shoulder a.The stopper B is then fitted in position by placing the knob b in thevertical portion of groove a, pressing it down until said knob meets thehorizontal portion, then turning the stopper until the knob traversesthe length of this part of the groove. A prepared cement or othersuitable material is then poured into the mouth of the groove, fillingit and sealing the stopper in position. It will be seen that when theknob 6 reaches the extremity of the horizontal portion of groove (0 thecutunder portion of stopper B will register with The the mouth a andform a passage-Way for the escape of the liquid. As the bottle is tiltedthe valve assumes the position in Fig.6,caused by the pressure of theoutflowing liquid upon it and upon the stopper F. The flat spring alimits the outward movement of the valve as against the liquid-pressureby coming in con tact with the lower end of the funnel; but shouldabnormal pressure be usedas. for example, by any one attempting to liftthe valve off its seat -the spring 6 yields to greater pressure and isbowed, as shown in dotted lines in Fig. 1, its arm ends passing over theledge as the stopper F is drawn up and closes the lower end of funnel.Thus the stopper may be securely locked in position. Said ledge may beomitted without departing from my invention, as generally the arms ofthe spring may give sufficient bind against the wall of the funnel toprevent stopper F being displaced when once pulled up. When the modifiedform of stopperGr is used, the cone-shaped cup when pulled up forces thestopper in the lower end of the funnel or shell, while the mouth of saidcup fits over and around said lower end. The spring a may be dispensedwith when this form of guard-stopper is used.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. In a bottle-closure for non-refillable bottles, the combination ofaneck having an an- I nular shoulder an offset or lip forming a mouthand an L-shaped groove,and a stopper having a lateral projection thereinwhich registers with said L-shaped groove forming a bayonet jointtherewith and a cut-under portion which registers with said lip to forma tortuous passageway leading into' the neck of the bottle.

2. A non-refillable bottle having a funnelshaped valve-shell and a valvewhich seats in the contracted portion of the side walls of the shellhaving a depending valve-stem adapted to project below said shell and astopper fastened to said projecting end of the stem adapted to close thelower end of the shell.

3. A non-refillable bottle having a tapering valve-shell and a valvewhich seats itself in the side walls of the same, a washer fastened tothe lower end of said shell forming a tight joint with the neck of thebottle, a stem depending from said valve having a stopper suspendedtherefrom which hangs below the shell and. adapted to close the lowerend thereof, and a spring-arm secured to said stem cross ing the same atright angles adapted to limit the normal play of the valve, yield toabnormal pressure and lock said stopper in position when drawn up intothe shell.
